Mattndew76, if you make me beautiful caliper brackets to mount my Mazda FC3S 4-pot calipers on my 510 spindles, I will let you touch any one of my rare parts from Japan for 10 minutes.Oh, and I'll pay you too.

Well, I wasn't the one crying "R&D rip off & duplicate."Feel butthurt, now?

Nah, just mystified as to why you would want to denigrate one of the people who has kept the 510 alive and fast.What kind of development work have you done lately?Us old dudes don't stand a chance against such a word wizard anyway.
